“I always use Eheim products as I find them to be one of the best on the market, however this pump was a massive disappointment! The head height I was pumping up to was 50cm and it couldn課ェt even cope with this! A real shame as 300lph was perfect for what I needed. I課ェm currently running an old Aquaone pump rated the same and it課ェs having no trouble at all. I課ェd recommend the 600 over this any day if you actually want to pump water upwards!!”
